ANCI-IOR FOR FLOOR SLEEPERS. Y

Application sied AFebruary 12, 1e27. serial No.` ieacsa The main objectsof thisA invention are to provide improved means for supporting andanchoring floorV sleepers used 1n concrete construction Work; ,toprovide improved means for spacing thesupporting means to insure auniform spacing of the sleepers; to provide improved fastening means forsecuring the sleepers to the supports; andto provide a device of thiskind which combines the supporting, anchoring andspacing means in aunitary structure which is durable and comparatively inexpensive.

Illustrative embodiments of this invention are shoWnin theaccompanyingdrawing, Wherein,- Y v n n Fig. 1is a vertical section of aconcrete slab on which floor sleepers are anchored by means of one formAof anchoring device which is shown in perspective,y part of the slabbeing-broken away for the salie of clearness. f Y f Fig. 2 is:aperspective of one of the fingers shown in Fig. 1 for fastening thesleepers to the spacer. l Fig. 3 is a view similar to Fig. 1, but

, tening and supporting means. Y,

Fig. 4 is a perspective of" one of the Wire fasteners shown in Fig. 3.-.A

Fig. 5 is an enlarged-detail in elevation of one of the foldedportionsof the spacer shown in Fig. 3, as it appears before insertion of theWire fastener.

, In the forms shown, the improved anchors are'used for supporting fioorsleepers 1', which are arranged horizontally on a concrete slab 2. Thesleepers are disposed in substantially parallel spacedrelation to form awooden frame structure to which thevusual ioor boards are nailed.y n n 1In the embodimentsillustrated, the anchor comprises a flat strip ofmetal, of substantially uniform cross sectionthroughout its length,Which is adapted to rest upon the top of theconcreteslab. Formed atregular intervals along the strip are legs which are em-y bedded in theconcrete for anchoring the device to the slab. Fastening means'arel secured to the leg portionsand projectV up- Wardly into position forattachment tothe sleepers. V- 'Y In Vthe form shown inFig.` 1, thevdevice comprises a strip 3 having portions thereof folded uponthemselves to provide a plurality of legs 4, which are arranged'in pairsat regular intervals along' the strip. Each leg sleepers.V

spaced apart slightly to provide seats 7 kfor f L-shaped fasteners S.To-securev the fasteners against accidental lateral displacement invtheir seats, they may be spot Welded kto the Yupright portions 5 of thelegs, as shown at 9. Y

The fasteners 8 project above the strip 3 to provide fingers 10,.havingaperturesll to receive'n'ails 12, for attachmentl to t-he sleepers. Thefingers 8 and intermediate portions 13 of the strip form substantiallyU-shaped seats for the sleepers.. The portions of the strip betweenadjacent pairs of legs provide spacers. 14k-for spacing Ythe In thedevice comprises a strip 15 having portions thereof folded tovsubstantially W-shape and adjacent their upper ends to provide gudgeons20, in which are hinged substantially U-shaped Wire fasteners 21.2'. Theendsof thel fasteners 21 are bentv to formeyelets22l to receive nails 23for vattachment to the sleepers.

VThe portions of the strip 15, located between the legs 16, form bearingsurfaces or seats 24C for the sleepers. 'Ihe intermediate portions ofthe strip form spacers 25 for spacing the sleepers.

In operation, after the concrete has been poured, and before it has'.set, the spacers are placed on the surface of the slab Wit-h the legsembedded in the concrete. After the concrete hasV set, the sleepers areplaced ink position and nailed to the upright fingers.

Although but certain specific embodiments form shown in Figs. 3, 4 and5, their 'then bent toprovidefL-shaped legs 16 hav- .Y

of this invention have been'herein shown and Y described, it Will beunderstood that numerous'details of the construction shown may beValtered or omitted Without departing from the spirit of this inventionas defined bythe following claims. l

YI claim: x v

VLA device of the class described com- -prisingastrip having a portionthereof fastening means supported in said seat and projecting beyondsaid leg for attachment to a bar resting on said strip.

2. A device of the class described coinprising a strip having a portionthereof folded upon itself and projecting outwardly to one side of saidstrip to forin a supporting leg with opposed portions of the foldedparts thereof spaced apart to provide a seat, and fastening meanssupported in said seat and extendino' beyond the plane of said strip forattachment to a bar resting on said strip.

3. A device of the class described comprising a strip adapted to supporta bar, said stiip being folded upon itself at points spaced apartlongitudinally of the strip to form a pair of spaced supporting legs,opposed portions of the folded parts of said egs being spaced apart toprovide seats, and fastening means supported in said seats and havingspaced lingers adapted for attachment to opposite sides of the bar.

4. A device of the class described compris ing a strip folded uponitself at points spaced apart longitudinallyy thereof to forni a pair ofspaced supporting legs.` opposed portions of the folded parts of saidlegs bcing spaced apart to provide grooves, and a pair of fingerssupported 1n said grooves and projecting beyond the plane of said strip,said fingers and the intermediate portion of said strip forming asubstantially `U-shaped seat for a bar.

5. A device of the class described cornprisinfr a strip folded uponitself at points spacedD apart onfritudinally thereof to forni a pair ofspaced3 supporting legs, opposed portions of the folded parts of saidlegs being spaced apart to provide grooves, and a pair of fingerssupported in said grooves and projecting beyond the plane of said strip,said fingers and the intermediate portion of said strip forming asubstantially U-shaped4 seat for a bar, said stri extending outwardly onopposite sides of said seat to piovide spacers. i

6. A device of the class described coinprising a strip having a portionthereof folded upon itself to form a supporting leg with opposedportions of the folded parts thereof spaced apart to provide a seat,said leg having a portion bent transversely thereto to forni a foot, andfastening means supported in said seat and projecting beyoud said legfor attachment to a bar resting on said strip.

7. A device of the class described comprising a strip adapted to supportbars, said strip being folded upon itself at points spaced apartlongitudinally of the strip to forni supporting legs, op osed portionsof the folded parts of said cgs being spaced apart to provide seats,.andfasteninff means supported in said seats and adapteda for attachment tothe bars, the ortions of the striplocated between sait legs formingspacers for spacing apartthe bars.

8. In a device of the class described, the
